- Irritant / corrosive response data:
- Injection of the conjunctival blood vessels was observed in two rabbits one hour following instillation of test item, and continued in one animal at the 24 hour examination. A crimson-red conjunctival appearance and very slight chemosis and discharge were observed in the remaining rabbit at the one hour examination; injection of the conjunctival blood vessels persisted in this animal to the 48 hour assessment.
- Other effects:
- Instillation of the test material caused practically no initial pain response.
The eyes of all rabbits were overtly normal by the 72 hour examination.

Applicant's summary and conclusion
- Interpretation of results:
- not irritating
- Remarks:
- Migrated information Criteria used for interpretation of results: EU
- Conclusions:
- Under the conditions of this test, the test item was classified as 'non-irritant' to the eye.
- Executive summary:
The potential of test item to cause damage to the conjunctiva, iris or cornea was assessed in three New Zealand White rabbits based on OECD 405, each subject to single ocular instillation of 100 mg of the test material. Ocular reactions were examined 1, 24, 48 and 72 hours after treatment. Injection of the conjunctival blood vessels was observed in two rabbits one and/or 24 hours following instillation. The third rabbit showed a crimson-red conjunctival appearance, slight chemosis and discharge at the one hour examination and injection of the conjunctival blood vessels up to the 48 hour assessment. The eyes of all rabbits were overtly normal by the 72 hour examination. Instillation of the test material caused practically no initial pain response. Under the conditions of this test, the test item was classified as 'non-irritant' to the eye.
